isGenAI.com · Free AI file detector

Upload an image file and isGenAI checks it for AI in one pass: Content Credentials (C2PA), AI-generated labels, saved prompts and settings from AI image tools, and AI statements in its metadata. Every finding names where in the file it was found.

Free. No account. PNG, JPEG, WebP, AVIF, TIFF up to 20 MiB. Private by default.

What happens when you upload a file

  1. The file is parsed, not judged by eye. isGenAI reads its metadata blocks: PNG text chunks, JPEG APP segments, WebP chunks and embedded C2PA manifests.
  2. AI records are matched. Signed Content Credentials, the IPTC digital source type, AI labels and generator settings are reported separately, so you can see which claim is signed and which is plain text that anyone could edit.
  3. You get a report you can retrace. Each finding quotes the record and its location, with a clear note when the copy carries no AI evidence.

Getting the most reliable result

Upload the original file from the camera, the AI tool or the sender, not a screenshot or a social-media download, because those usually lose their records. To see the full chain of a Content Credentials manifest, use the C2PA checker; to read just the saved prompt, use the image prompt extractor; and to inspect every metadata field, use the EXIF viewer.

Checking many files? The free isGenAI API takes the same uploads, and AI assistants can call it through the isGenAI MCP server.

Questions about checking a file for AI

Which files can I upload to check for AI?

PNG, JPEG, WebP, AVIF and single-page TIFF images up to 20 MiB. For documents and other text, paste the text into the text tab; for a web page or online file, paste its public link.

What does the AI file detector read inside the file?

It reads the records a file carries: C2PA Content Credentials and their signatures, IPTC and XMP AI labels, EXIF metadata, and the prompt, model and settings saved by AUTOMATIC1111, ComfyUI, InvokeAI or NovelAI. Each finding names the part of the file it came from.

Is my uploaded file stored or made public?

Uploaded files are checked privately by default and no public report is created unless you choose to publish one. No account is needed.

Why does my AI image show no AI signal?

Many apps and social networks strip metadata when a file is saved, screenshotted or reposted. A copy without records carries no evidence either way, so upload the original download whenever you can.
